Aprimitive economy depends on two basic? goods, yams and pork. production of 1 bushel of yams requires 1/8 bushel of yams and 1/2 of a pig. to produce 1 pig requires 1/6 bushel of yams. find the amount of each commodity that should be produced to get the following.
? (a) 1 bushel of yams and 1 pig
? (b) 200 bushels of yams and 60 pigs
(a) find the? input-output matrix,? a, and the demand? matrix, d, for this economy.
the? input-output matrix is

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )
